The gear change scheme

At transfer inclusion press a coupling pedal, then smoothly release. It is not supposed to hold a foot on a pedal of coupling during movement, infringement of normal work of coupling otherwise is possible. Also is inadmissible to put the car on transfer to keep on lifting, for this purpose use a manual brake.

Too early switching on the raised transfer and too later switching on the lowered leads to an overload of the engine and occurrence of knocks. The frequent gear change on maximum permissible speeds of movement is at the bottom of the accelerated deterioration of the engine and the raised expense of fuel.

Councils about driving

If inclusion of a backing from neutral position of the lever inconveniently for an instant release a pedal of coupling and repeat inclusion

Do not include 5th transfer at trailer towing to avoid increase in a brake way of the car against norm.

System of blocking of interaxal differential (for cars with a drive on all wheels)

The system of blocking of interaxal differential is intended for increase of traction qualities of the car in following situations.

If forward or back wheels come off a road covering, or adjoin to a slippery covering.

One of four wheels comes off a road covering, or adjoins to a slippery covering.

Preventive measures

At non-uniform deterioration of forward or back wheels smoothness of blocking or разблокирования interaxal differential can be broken.

Before differential blocking be convinced that wheels do not revolve.

Unblock differential right after usings blocking.

In those cases when the control lamp on the panel of devices does not light up, or dies away only if after repeated pressing of the button of blocking of differential the car passes small distance, address in service of car-care centre for check of an electric chain and the blocking mechanism.

Security measures

Under normal conditions movements it is necessary to unblock interaxal differential as at blocking of semiaxes passage of turns is at a loss.

For differential blocking:

1. Press a pedal of a brake and stop rotation of wheels.

2. Put forward wheels as it is possible more close to driving position on a straight line.

3. Press the button of blocking of interaxal differential. On the panel of devices the control lamp should light up.

At differential blocking the control lamp continues to burn.

In certain cases the lamp does not light up at the moment of button pressing.

To unblock differential:

1. Turn forward wheels as it is possible more close to driving position on a straight line.

2. Repeatedly press the button of blocking of interaxal differential. The control lamp on the panel of devices should go out. If the lamp does not die away, allow to the car to pass a little on small speed.
